MERRITT W. SMITH, OF TROY, PENNSYLVANIA, ASSIGNOR TO JOHN A. PARSONS, OF TROY, PENNSYLVANIA.

OILING SYSTEM FOR ENGINES.

To all whom it may concern:

Be it known that I, MERRITT W. SMITH, of Troy, in the county of Bradford and in the State of Pennsylvania, have invented a certain new and useful Improvement in Oiling Systems for Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in Which Figures 1 and 2 are respectively side and front elevations of an engine embodying my invention; Fig. 3 is a sectional view of the valves of the oil pump; and Figs. 4, 5 6 and 7 are detailed views.

The object of my invention has been to provide a system for oiling engines, which shall have, among others, the following advantages: that of having a simple and effective pump and valves conveniently located for driving and inspection; that of having a distributing head for the oil, which shall be effective and compact; that of having panels inclosing the frame, which shall direct the oil which may be thrown by the crank and cross-head into a reservoir in the base of the engine; and that of having means for removing drops of oil that may adhere to the eccentric, and prevent their being spattered by centrifugal action. And to such ends my invention consists in the oiling system for engines hereinafter specified.

In carrying my invention into practice in the instance chosen for illustration (which shows its application to a vertical engine), the frame of the engine is provided with a reservoir 10 in the base, in which may be put oil for lubricating the engine. Suitable means for draining off the oil may be provided. A strainer 11 is supported in the reservoir as by a forked bracket 12, at such a level as to be below any water of condensation that may accumulate in the reservoir. This strainer is connected by a pipe 12 to a union 13, preferably having ground joints, to permit the strainer to be readily removed and cleaned. A pipe 14 extends from the union up to the valve box of the pump. Such box has a vertical cylindrical suction chamber, whose lower end has the pipe 14 secured thereto, and a similar pressure chamber 15, the two chambers being connected by a passage 16, which passage also communicates, by a passage 17 withtheinterior of the pump cylinder 18. In the suction chamber below the passage 17 is a pref- Specification of Letters Patent.

erably beveled seat 19 for a ball 20, which ball acts as a valve. The upper end of the suction chamber is closed by a nut 21, having a cylindrical lip or flange extending from its underside down to a level below which the ball cannot pass, the lip being provided with a groove or passage 22 to permit oil to escape. The lip keeps the ball in position and prevents its being carried away by theoil, while at the same time it permits the oil passages to be made large. In the pressure chamber, a seat 23 is formed at a level above the passage 17, and of such shape as to properly hold a ball 24 that also acts as a valve. The ball 24 is maintained in position by a lip 25 011 a nut 26 that closes the pressure chamber, the lip having a groove or hole 27 to permit the passage of oil to a pipe 28, l ading to a sight feed 28 and thence to dist ibuting head 29, to be laterdescribed. The ump chamber is in the present instance bolted to the under side of the steam chest of the engine, and is a simple cylindrical passage in which is mounted the pump piston 30. The piston 30 is preferably a rather loose fit for the cylinder, so that oil may escape from the cylinder and work down the piston for a purpose later to be described. The piston 30 is bolted to an angle plate 32 that is secured to a wrist pin 33, that is clamped to the.

valve stem 34, the wrist pin having thereon a head 35, on which is secured the eccentric rod 36. The upper nut 37, by which the pump piston is secured to the angle plate is dished on its upper surface, and a cross hole 38 is formed in the plunger connecting with a vertical hole 39, also formed in the plunger, so that oil trickling down the plunger or piston may pass through such holes and drip on to the head 35, the oil passing through a hole 40 formed in the said head, and entering an alining hole 41 in the wrist pin, hole 41 communicating with a horizontal hole 42, which opens into a groove 43 along the surface of the valve stem, oil thus being communicatedto the valve stem and being allowed to run down the stem to lubricate the stem in its bearings. The distributing head is preferably an arc-shaped casting, having a chamber or passage formed therein for the oil. This head is made in the form of an arc, because it can thereby surround the stuffingbox on the cylinder head, both to occupy a convenient location and not to be cumbersome. On the under side of the distributing head are a series of couplings for pipes which convey oil to various parts to be lubricated. Two of these ipes, 40 and 41 respectively, supply oil to tie cross-head guides. Oil for the main bearingsis supplied by two other of the tubes, 44 and 45, and a fifth tube 46 supplies oil to the cross-head pin, the oil being caught in a cup 47 and entering the pin through an oil passage in its center. A portion of the oil in the cup also escapes through a hole in its bottom into a funnel which is attached to a tube 48 that is secured to the connecting rod, and that leads oil into the crank pin box. The eccentric is oiled through one of the main bearings, the oil reaching the eccentric strap by a groove 48 in the eccentric and thence through one or more openings 48 diverging from the main shaft. A shield 49 incloses the eccentric, but notwithstanding oil would be spattered under high speeds, especially with horizontal engines, by coming in contact with the eccentric rod, which tends to lead it away from the eccentric. To preventthis a scraper 50 is attached to the eccentric strap in position to nearly touch the eccentric, and to remove any oil from the external periphery of the eccentric. There is also attached at the base of the rod a small shield 51 that intercepts any oil that may remain on the eccentric rod. The openings at the sides of the frame between the guides and the crank shaft bearings are closed by panels 52, each panel having handles 53 that turn clamps 54 on the inside of the panel, the clamps fitting against the legs of the frame. These panels each have ribs 55 and 56, which prevent the oil from dropping down the center, and conduct it toward the outer edges, where it may drop'into the reservoir. Without the said ribs, oil thrown from the cross-head, would follow down the inner surface of the panel and escape to the outside of the engine over the main bearing caps. Each panel is also provided with substantially vertical ribs 57 to prevent the oil from passing out through the joint which the panel makes with the frame.

In the operation of my oiling system, the reservoir is supplied with a proper quantity of oil, and the engine being set in motion, the oil will be seen at the sight feed after a few revolutions of the engine. The oil will be supplied under pressure to the. distributing head, and pass through the several pipes to the various wearing .surfaces. The pressure prevents the oil from becoming clogged, insuring the continuous flow of the oil. It will be observed that every part of the oiling system is accessible, and that the system is simple. The pump is very conveniently driven from the eccentric rod, avoiding complication.

While I have illustrated my system as ap plied to avertical engine, it is to be understood that it is applicable to many other forms of engines, and I desire that my claims shall not be limited beyond the requirements of the prior art, and the necessary intendment of the claims.
